The RDS Right-Sizing Recommendations provide you with a list of RDS instances that can be optimized. The Umbrella Cost engine takes into account historical usage patterns and performance metrics, and provides you with data-driven recommendations according to your requirements.

When considering the cost of Amazon RDS, it is essential to understand the key cost components associated with it. AWS RDS cost is primarily influenced by the following factors:

Instance Types: The choice of instance types determines the underlying hardware, compute power, and memory allocated to your database. Different instance types have varying costs, and selecting the right one based on your workload requirements is crucial.
Database Engine: The database engine you choose, such as Amazon Aurora, MySQL, PostgreSQL, or others, can impact cost due to differences in licensing fees, storage requirements, and performance characteristics.
Provisioned Storage: AWS RDS provides storage for your databases, and the amount of provisioned storage directly affects the cost. It is essential to estimate your storage needs accurately to avoid unnecessary expenses.
Multi-AZ Deployment: Enabling Multi-AZ (Availability Zone) deployment enhances high availability but comes at an additional cost. This feature replicates your database across multiple AZs, ensuring automatic failover in the event of an infrastructure issue.

RDS Right Sizing

This recommendation identifies if the RDS instances have cheaper suitable alternatives considering the instance's current utilization + CPU spare capacity on top.

RDS Generation Upgrade

Suggest using the latest generation of instances to get the best performance and pricing.

RDS Provisioned IOPS

This recommendation identifies Provisioned IOPS that can be decrease .

RDS Reserved Instance

This recommendation recommend on RI purchase and is based on customer historical usage.

RDS Instance Idle

This recommendation identifies RDS instances with consistently low utilization, indicating they may be idle or over-provisioned.

RDS Storage Type Change

This recommendation identifies RDS storage type that can be changed, the recommendation analyzes your current database storage configuration and suggests migrating to a more cost-effective or performance-aligned storage option.

RDS Aurora I/O Optimized

This recommendation identifies Amazon Aurora clusters where switching to the I/O-Optimized configuration can reduce costs for I/O-heavy workloads.
